Jennifer Lawrence and Alison Brie in...Muffy the Vampire Slayer!

Just a few years before her star-making turn in Winter's Bone, Oscar winner Jennifer Lawrence cameoed alongside Community's Alison Brie in an unaired Comedy Central pilot -- more specifically, in a sketch called "Muffy the Vampire Slayer" -- where Brie parodies Sarah Michelle Gellar's Buffy Summers.

Courtesy of TheWrap, Muffy was a segment in Not Another High School Movie, a 2007 pilot that Comedy Central never picked up to series. The parody show was to capitalize on the Scary Movie/Epic Movie/Not Another Teen Movie "craze" at the time.

Watch a young Brie stab a janitor in the heart, and see Lawrence cameo just in time to get hit on!

Okay, so it's not a complete surprise that this series wasn't picked up.
